Schizophrenia is a common psychiatric disorder that occurs mainly in adolescence, characterized by positive and negative symptoms. Despite a large number of studies, much remains unknown about the molecular etiology of schizophrenia. In this study, we applied iPSC technologies to generate patients' live neuronal cells that enable us to precisely analyze the disease-associated neuronal phenotype. We analyzed the neural function of iPSC-neurons derived from patients from a family with multiple occurrence of schizophrenia and other patients. In these neurons, we found that the impaired gene expression, splicing events and synaptic functions, all of which may be associated with schizophrenia. These results imply that iPSC-derived neurons of patients with schizophrenia provide important insights into the development of new treatment strategies and biomarkers for diagnosis and treatment efficacy.
